This invention relates to an improved apparatus for directly detecting and monitoring uterine bio-electrical activity "in vivo" characterized by an electrode carrier in the form of a cup shaped to conform to the patient's cervix and hold the electrodes contained therein in such intimate contact with the cervical tissue that an impedance match therebetween is established and maintained at a level of less than 10,000 ohms without the aid of suction. The invention is also characterized by non-invasive, broad-headed, low profile solderless electrodes. The invention is further characterized by the use of a multiple-electrode pattern containing at least three electrodes arranged such that separate and distinct current paths exist between each electrode and the others whereby discrete signals can be detected, monitored and charged. Additionally, the invention encompasses the novel method of measuring uterine electrical activity which comprises monitoring and recording the electrical potential along at least two discrete current paths simultaneously with reference to a common time base.
